To all whom may concern:

Be it known that T, ALBERT R. om, a

other suitable containers, and more particularly to a fastener for aslidable closure.

The principal object of the invention is to provide a highly novelfastening means for theslidable closure which is simple in itsconstruction, efficient and reliable in its operation, strong, durable,easy to manipulate, not likely to easily become out of order, compactand convenient, and otherwise well adapted to the purpose for which itis designed.

ith the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangen'ient' of parts as willbe hereinafter more fully described and claimed. I

In the drawings Figure 1 is an elevation of the box or containerembodying the features of my invention.

Figure 2 is a fragmentary enlarged elevation thereof looking to theright of Figure 1 and showing the fastener in detail, and

Figure 3 is a detail section through the fastener.

Referring to the drawing in detail it will be seen that 5 designates anysort of con tainer which is provided on one side with a longitudinallyor transversely extending cleat 6 adjacent the upper edge and on itsopposite side with a similarly extending cleat 7 spaced from the upperedge. A bar 8 is attached to one edge of the cover 9, depends therefrom,and terminates at its bottom end in a reetangularly disposed extension.9 fitting under the cleat 6. A bar-.11 is mounted at the opposite edgeof the cover 9 and slides on top of the cleat 7. An angle plate 12 isfixed to the cover 9 and to the bar 11. A pair of links 13 and 14 arepivoted at spaced points to the plate 12, and convergedownwardly towardeach other. A clamping; device indicated generally by the letter A ispivotally engaged with the description.

lower ends of the links 13 and 14. This clamping device A includes acasing 16 hav ing slidably mounted therein the shank 17 of a shoe 18adapted to bear against the under surface of the cleat 7 This shank 1 7is provided with an oval shape opening 20 in which is movable the cam 19on the shaft 21 journaled through the casing and operable by the crankWhen the crank 22 is in the position shown in .the drawings, the shoe 18is held in frictional engagementwith the under surface of the cleat 7,thereby preventingt sliding of the cover 9. Thus the cover 9 may beheldin a fully closed position against accidental displacement and may hesimilarly held in a partially open position. To slide the cover it isonly necessary to swing the crank 22 in the position indicated by thearrow in Figure 3.

It is thought that the construction, operation, and advantages of thisinvention will now be clearly understood without a more detaileddescription thereof. The present embodiment of the invention has beendisclosed in detail merely by way of example since in actual practice itattains the features of advantage enumerated as desirable in thestatement of the invention and the above It will be I apparent thatchanges in the details of construction and in the combination andarrangement of parts may be resorted to without departing from thespirit or scope'of the invention as hereinafter claimed or sacrificingany of its advantages.

Having thus descrihec the invention, what I claim as new is 1. Incombination, a container, a cover slid-ably nmunted on the container, acleat on the container, a pair of links engaged with the cover, a casingsupported by the links, a shoe, a shank extending from the shoe intothecasing, a cam in the casing for pushingthe shank therefrom andforcing the shoe into frictional engagement with the cleat, and meansfor opera-ting the cam.

A fastening device for a container; wherein the container includes aslidable cover; con iprising a cleat adapted to be mounted on thecontainer, a pair of links adapted to be engaged with the slidablecover, and a clamp supported by said links and adapted to engage undersaid cleat to frictionally engage the same to prevent the sliding of theslidahle cover.

..a combination, a. container, at cleat on one side of the container, aslidable cover on the container, a bar fixed to the cover and slidableon the top of the ole-at, an angle plate attached to the edge of thecover adjacent the bar, a pair of links attached to the angle plate, anddepending downwardly therefrom and converging toward their bottom ends,a clamping mechanism engaged with one link and adjustably engaged withthe other link.

4:. In combination, a container, a eleat on one side of the container, aslidable cover on the container, a bar fixed to the cover and slidableon the top of the cleat, an angle plate attached to the edge of thecover adjacent the bar, a pair of links attached to the angle plate, anddepending downwardly therefrom and converging toward their bottom ends,a clamping mechanism engaged with one link and adjustably engaged with 1the other link, said clamping mechanism including a casing, a camrotatable in the easing, means for rotating the cam, a shank slidable inthe casing and having an oval shaped opening for receiving the cam, anda shoe on the shank adapted to engage the under surface of the cleat.

In testimony whereof I afiix my signature.

ALBERT R. XVOLF.
